Notes

• See the references above for additional technical detail on this error.
• UPDATE (10/11/12): I've added some additional references you may find useful on this error.  Note that it's not limited to just the pages discussed above but may occur on other pages and involve other web parts.  The error does not appear to indicate actual loss of functionality that I have been able to tell and thus I recommend disabling the rule for now, as I do for my customer.
• UPDATE (3/4/14): I have found that just navigating to the page isn't always sufficient to resolve this error.  Instead, I found that refreshing the page once or twice after navigating to it ensured that the error was resolved.
• UPDATE (3/17/14): This error re-appeared. Performed same procedure to resolve. Unclear why the circumstances generating this error should manifest themselves again.
